Smoking-related interstitial fibrosis, abbreviated SRIF, is a benign pauci-inflammatory scarring associated with smoking.
General
- Associated with emphysema and respiratory bronchiolitis.[1]
Clinical:
- Much better prognosis than usual interstitial pneumonia (UIP) with emphysema - five year survival 86% (SRIF) versus 41% (UIP).[2]
Gross
- Subpleural and centrilobular predominance.[1]
Microscopic
Features:[1]
- Septal thickening of alveoli with:
- Thick collagen bundles - may be described as "ropy".[3]
- Hyperplastic smooth muscle fibres.
- Minimal inflammation.
DDx:
- Usual interstitial pneumonia - has inflammation.
